Support haste 5

[rabauss]

I continued the work of @qzminski to support haste 5

• [x] Refactor usage of \Haste\Util\StringUtil to \Codefog\HasteBundle\StringParser
• [x] Refactor usage of \Haste\Http\Response\Response to \Symfony\Component\HttpFoundation\Response
• [x] Upgrade to menatwork/contao-multicolumnwizard-bundle
• [x] Fix compatibility of export with PhpSpreadsheet
• [x] Drop support of phpoffice/phpexcel
• [x] Refactor haste IO to PhpSpreadsheet (Csv now also via spreadsheet)
• [ ] Export with template should be tested - I had no working config
